\(2019:0,2+2019+2019:0,25\)
\(=2019:\frac{2}{10}+2019+2019:\frac{25}{100}\)
\(=2019:\frac{1}{5}+2019+2019:\frac{1}{4}\)
\(=2019\cdot5+2019+2019\cdot4\)
\(=2019\cdot(5+1+4)=2019\cdot10=20190\)
Dấu chấm là dấu nhân nhé
2019:0,2+2019+2019:0,25
=2019 x 5 +2019 +2019 x 4
=2019 x (5+1+4)
=2019 x 10
=20190
2019 : 0,2 + 2019 + 2019 : 0,25
= \(2019:\frac{1}{10}+2019+2019:\frac{1}{4}\)
=\(2019\times10+2019+2019\times4\)
= \(2019\times\left(10+1+4\right)\)
= \(2019\times15\)
= \(30285\)
= 2019 nhân 5 + 2019 + 2019 nhân 4
= 2019 nhân (5 + 4 +1 )
= 2019 nhân 10
= 20190
hocj tốt
2019 : 0,2 + 2019 + 2019 : 0,25
= 2019 x 5 + 2019 x 1 + 2019 x 4
= 2019 x ( 5 + 1 + 4 )
= 2019 x 10
= 20190
~ Hok tốt ~
2019 : 0,2 + 2019 + 2019 : 0,25
= 2019 x 5 + 2019 + 2019 x 4
= 2019 x ( 5 + 1 + 4 )
= 2019 x 10
= 20190

Trả lời:
\(2019:0,2+2019+2019:0,25\)
\(=2019:\frac{2}{10}+2019+2019:\frac{1}{4}\)
\(=2019.\frac{1}{5}+2019+2019.4\)
\(=2019.\left(\frac{1}{5}+1+4\right)\)
\(=2019.\left(\frac{1}{5}+\frac{5}{5}+\frac{20}{5}\right)\)
\(=2019.\left(\frac{26}{5}\right)\)
\(=....\)
\(2019\div0,2+2019+2019\div0,25\)
\(=2019\times5+2019+2019\times4\)
\(=2019\times\left(5+1+4\right)\)

=20190
chúc bn
học tốt
Chết rồi mk làm nhầm rồi. Huhu
= 20190
2019 : 0,2 + 2019 + 2019 : 0,25 = 20190
hok tốt ^^
